YouTube - on 4K

Question

Youtube runs only in 2560 x 1440. No way to change the resolution to 4k.

Just bought LG 50UH5500 4K with WebOS 3.0 and am trying to figure out how to run youtube in 4k with in built app.

Has anyone have resolution problem using YouTube on 4k TV? I checked 'more info" and it shows me current resolution of YouTube, which is 2560 x 1440 instead of 4k and there is no option to change the resolution.

I have to use web browser and only then i can see it in 4K. However, the default is set to 1080 on web browser, so have to manually change it to 4k evey time i use youtube on web browser.

Wish there was an easy way to set defaults and the YouTube app with an option to change the resolution. I do have internet speed of 25 Mbps, which i suppose is capable of 4k.

Mine was resolved after upgrading my internet speed from 25 Mbps to higher. Looks like you need at least 30 Mbps speed which does not seem correct. Since Netflix says 20-25 Mbps is good enough for their 4K content. I had a doubt with their content though.

After increasing my internet speed, I feel Netflix is now in 4K which was not while on 25 Mbps. However, it's hard to find out their resolution since webos app for Netflix does not show the resolution.

Not sure where the problem lies but looks these webos apps are not ready for production. It's filled w bugs. My google play crashes and freezes or sound stops after watching a movie for 30 mins or so. I repent getting LG.

Hi there, I've recently bought a TV 49sj810v, and I can't change a playback speed for youtube videos via the Youtube app and the browser as well, how come? Why changing the playback speed is possible for my more older samsung tv with the only 1 core processor?

Hi
I have a LG Smart TV LJ550V
After updating the webos to 04.70.30 in the night I watched some YouTube videos and turned off the TV, in the next day I tried to open the YouTube app and the TV said that the YouTube app isn't supported and disappeared and I cant find it on LG store.
Can anyone help me please

Short answer: Something on my network is causing the crashes.
I had an extra router, so I put it between my network and the TV.
Netflix no longer crashes, and other apps no longer give me the dreaded, "This app will now restart to free up more memory" error.

Longer answer: Netflix would regularly crash out to Live TV after 20-40 minutes of play. I've been on LG support with this for months. They've replaced the main board twice, and took it off-site where the problem could not be replicated.
I reset the TV and connected it to my smart phone data plan (luckily just upgraded to 10 GB). No crashes. Put the TV back on my network, crashed after half an hour.
I took the network cable out of the TV and plugged it into a spare WiFi router. This creates a small network of only one device (the TV). I no longer get crashes.
Unfortunately, this kills local network features like DLNA/Plex streaming and wireless display mirroring, but all Internet apps like Netflix and YouTube work flawlessly.
I plan to narrow down which device(s) on my network is the cause of the crashes, but after 10 months of fighting this I'm just going to enjoy some 4K streaming for a while. If I learn anything new, I'll post it here.

I have a 49UJ634V television. When I install the YouTube app from the content store the app starts to reboot with the pop-up “out of memory app will restart” but this is then with everything . Live-tv, guide, etc
this is a app problem beacause when I delete the app everything else works fine again.
